The failed climate models of the IPCC and NASA have revealed the terminal weakness of the AGW hypothesis - but new research and models are coming online that better explain global warming and climate change

Read here and here. The impressive success of the harmonic astronomical climate model (left chart) is in the realm of spectacular when compared to the robust, abysmal performance of the IPCC's (middle chart) and NASA's (right chart) traditional CO2-based climate models. The failure of the CO2-centric models is due in large part to their inability to reproduce the known decadal and multi-decadal oscillations that are part and parcel to the world's climate.

The significant failure of the IPCC / NASA climate models, and the AGW hypothesis they are derived from, is captured in its entire absurdity here. Literally, the avid proponents of the failed CO2-driven AGW hypothesis first admit to there being essentially zero warming over the last 10 years, and then try to rationalize the disappearance of warming with a diversity of speculations other than the obvious - that the current IPCC and NASA climate theory is bankrupt.

John Barnes, climate scientist: “If you look at the last decade of global temperature, it’s not increasing,” Barnes said. “There’s a lot of scatter to it. But the [climate] models go up. And that has to be explained. Why didn’t we warm up?”..."We do have satellites that can measure the energy budget, but there’s still assumptions there. There’sassumptions about the oceans, because we don’t have a whole lot of measurements in the ocean.”.

Robert Kaufman, climate scientist: "...released a modeling study suggesting that the hiatus in warming could be due entirely to El Niño and increased sulfates from China’s coal burning."

Martin Wild, climate scientist: "During the 1980s and ’90s, the rapid decline of air pollution in the United States and Europe dominated the world’s aerosol trends. While those emissions have continued to decline in the West, returns, from a brightening standpoint, ...“It’s not an obvious overall trend anymore,”..."

Susan Solomon, climate scientist: "“What’s really been exciting to me about this last 10-year period is that it has made people think about decadal variability much more carefully than they probably have before,” ...Solomon had shown that between 2000 and 2009, the amount of water vapor in the stratosphere declined by about 10 percent. This decline, caused either by natural variability — perhaps related to El Niño — or as a [negative] feedback to climate change, likely countered 25 percent of the warming that would have been caused by rising greenhouse gases..."

Kenneth Trenberth, climate scientist: "Until 2003, scientists had a reasonable understanding where the sun’s trapped heat was going; it was reflected in rising sea levels and temperatures. Since then, however, heat in the upper ocean has barely increased and the rate of sea level rise slowed,...they put forward a climate model showing that decade-long pauses in temperature rise, and its attendant missing energy, could arise by the heat sinking into the deep, frigid ocean waters, more than 2,000 feet down."

James Hansen, climate scientist: "All the climate models, compared to the Argo data and a tracer study soon to be released by several NASA peers, exaggerate how efficiently the ocean mixes heat into its recesses....that climate models have been overestimating the amount of energy in the climate,...“Less efficient mixing, other things being equal, would mean that there is less warming ‘in the pipeline,’” ....it also implies that the negative aerosol forcing is probably larger than most models assumed."

Graeme Stephens, climate scientist: "It suggests there isn’t a missing energy. Trenberth disagrees with this analysis, and it’s likely to be a question of ongoing debate."

Judith Lean, climate scientist: "The answer to the hiatus, according to Judith Lean, is all in the stars. Or rather, one star...Climate models failed to reflect the sun’s cyclical influence on the climate and “that has led to a sense that the sun isn’t a player,” Lean said. “And that they have to absolutely prove that it’s not a player.” According to Lean, the combination of multiple La Niñas and the solar minimum, bottoming out for an unusually extended time in 2008 from its peak in 2001, are all that’s needed to cancel out the increased warming from rising greenhouse gases."

Ben Santer, climate scientist: “All of these things contribute to the relative muted warming,”..."The difficultly is figuring out the relative contribution of these things. You can’t do that without systematic modeling and experimentation. I would hope someone will do that.”...“Even if you have the hypothetical perfect model, if you leave out the wrong forcings, you will get the wrong answer.”

John Daniel, climate scientist: “We make a mistake, anytime the temperature goes up, you imply this is due to global warming,” he said. “If you make a big deal about every time it goes up, it seems like you should make a big deal about every time it goes down.”

Conclusion: The failed climate models (that "scientists" from the IPCC and NASA livelihoods are dependent on) are based on a discredited CO2 hypothesis that is unable to explain the global climate's fluctuations. Newer models based on natural causations, be they of cosmic and/or earthly origin, are better able to explain global climate change, including decadal and multi-decadal temperature variation.
